Abstract

Abstract Reaction of 3, the N-Boc, O-tosyl derivative of phenylalaninol, with base leads to loss of the Boc and tosyl groups and formation of oxazolidinone 9. Similar reactions have also been examined. A mechanism to explain loss of the Boc group under basic reaction conditions is proposed.
